As predicted, by the end I was getting to be quite frustrated with its neverendingness, but I'm pleased with the final result. The unblocked version was nice, with a bit of a shell effect at the ends, while the blocked scarf is quite elegant. I'm sure my mother-in-law will appreciate the effort and I hope she'll feel spoiled - it's been a long autumn for her.
And just to complete the scarf-set (excepting the one which will now be for my gran's birthday in January), the 2nd & 3rd crocodiles were finished last Saturday:
The green croc either looks as though he's half asleep, or maybe he's enjoyed a Christmas tipple or two. I'm not sure!
